Twins outfielder Darin Mastroianni underwent a follow-up surgical procedure on his left ankle on Oct. 16, the team announced Tuesday.

The procedure was done to remove "fixation hardware" that was put in place during a previous surgery on May 5.

Mastroianni, who fouled a ball off his left shin during the final week of spring training, ultimately suffered a stress reaction in the left ankle that torpedoed his season. Mastroianni posted a .229 on-base percentage in just 73 plate appearances (30 games) with the Twins.

Also Tuesday, the Twins removed outfielder Wilkin Ramirez from the 40-man roster and outrighted his contract to Triple-A Rochester. Ramirez had been on the 60-day disabled list.

Ramirez, who missed the final 30 games with a fractured left tibia, is likely to opt for free agency after posting a .302 on-base percentage in 87 plate appearances in 2013. He missed more than 10 weeks following a May 25 concussion and subsequent setback.
